Waste plastic processing waste gas treatment process and waste plastic processing waste gas treatment complete equipment

Abstract

The invention discloses a waste plastic processing waste gas treatment process and waste plastic processing waste gas treatment complete equipment. The production process comprises: 1) dust removal, wherein the pollution on the catalyst of the subsequent process can be avoided; 2) degradation of pollution waste gas, wherein pollution waste gas is subjected to a reaction in a photocatalytic chamberso as to degrade into non-toxic and harmless gas; 3) separation of purified gas and catalyst, wherein a gas path is controlled by a valve device, and the circulation of the purified gas and the catalyst is achieved through the synergetic operation with the magnetic fields of magnetic field chambers; and 4) reducing of excess ozone, wherein the purified gas is discharged from the magnetic field chamber, and the reducing of excess ozone is achieved through a reducing filling layer. According to the present invention, various devices of the complete equipment are reasonably matched, the waste gas is effectively purified, and no secondary pollution is generated during the treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a process and equipment for treating waste gas from waste plastic processing. Background technique [0002] Plastic products are used in various fields, including construction industry, transportation, packaging, agriculture, daily necessities and medical care, etc. Now life is inseparable from plastics. With the rapid development of the output of plastic products in China, the disposal of waste plastics has gradually changed from traditional landfill and incineration to recycling and recycling. However, the processing of waste plastics will produce a series of high-concentration toxic and harmful exhaust gases, which seriously endanger the health of workers and affect air quality. Therefore, there is an urgent need for a technology and equipment for waste plastic processing waste gas treatment. [0003] The current technology for treating waste gas...

Problems solved by technology

[0003] The current technologies for treating waste gas either have high treatment costs or low efficiency in dealing with high-concentration waste gas. Photocatalytic technology is a green technology for treating waste gas, with a wide range of treatment, mild conditions, and simple equipment. It is expected to be used in the treatment of waste plastic processing waste gas , but the current photocatalytic technology has the following disadvantages:

[0004] First, the photocatalytic treatment time is short, and it is difficult to effectively remove high-volume, high-concentration exhaust gas. However, the concentration of exhaust gas generated by waste plastic processing is high, and the treatment efficiency of a single photocatalytic technology is low, and the purified exhaust gas is difficult to meet the emission standards.

[0005] Second, the combined photocatalytic technology can greatly reduce the concentration of photocatalytic waste gas by using other technologies, but usually requires the use of spray devices, etc., which is prone to secondary pollution and the transfer of pollution, not waste gas treatment the ultimate goal of

[0006] In summary, the existing photocatalytic technology is difficult to achieve low-cost treatment of waste plastic processing waste gas without causing secondary pollution. Research and invention of waste gas treatment technologies that are economical and environmentally friendly are conducive to promoting the recycling of waste plastics
